My invention relates to an improvement in floor construction for passenger cars, and particularly street cars. j

With cars having steel floors composed of plates supported Aon and riveted to cross bearers, considerable trouble is experienced and expense occasioned by reason of the uneven surface. It is practically impossible to plates lie perfectly flat, and the rivets projecting above the plates at the joints, cause expense in fitting the covering used for the floors. If wood is used as a covering, recesses must be cut in the 'underside of` the planks'wherever rivets project,

010V- with cork covering it is difficult and expensive to properly fit the cork over the joints in the plates.

The object of vthe present invention is to dispense with the ordinary cross bearers used in car ioor construction and. so construct the steel floor plates that they will be suiiiciently rigid to support the loads and at the same time obtain a smooth upper surface without Li-ints or exposed rivets; and it consists in the construction and arrangement of parts as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 of a car floor embodying 2 is a view of a part of my invention; Fig. F

as cross bearers and stiening members for the'plates 6. The overlapping edges 7 and secured together by rivets 9, which as shown, are located at the bottoms of the channels, thus leaving the upper surfaces of the plates flat and free from obstructions, and permitting the wood or other floor 10 to be placed in position and lie flat on the steel floor plates without any preliminary recessing for projecting rivets, or

trimming to accommodate projections at the rI`he wood or other covering is secured to the floor plates by screws 11 put in from the underside. i

If desired the plates 6 may be lightened considerably by punching holes therein as shown in Fig. 3, the holes being at regular or irregular intervals apart and of the same or different sizes. v i

In Fig. 4 I have shown the plates 6 having depending channeled projections running crosswise the car, as in Fig. 1, secured to plates having depending channeled projections running lengthwise as in Fig. 2. It is sometimes necessary to do this at points over the motors and wheels when the latter in pivoting would come in contact with the channels. In this form the plates 6a are identical in construction with the plates 6 as previously described except that the channels formed at the edges of said plates extend longitudinally the car'instead of transversely as in Fig. 1, and when the two forms are combined in one oor,`the edges of plates 6 adjacent the plates 6a, are bent into L- shape, the horizontal members 13 of the L- shaped ends resting under and forming supports for the channeled projection of the plates 6a, the adjacent end of the plate 6 be ing reinforced and strengthened by the reinforcing channel bar 14. 'Ihe ends of the plates 6a at the channeled projection, are cut away as `shown -in Fig. 5, the projecting end webs 15 formed by cutting away the corners of the plate 6a, being bent downwardly vertical members of After the parts have vbeen thus assembled, they are secured by rivets 16 passing through the bottoms of the channels of the plates 6hl and through the horizontal members of the bent ends of plate 6, and also by the rivets the depending end webs 15 of plate 6, the vertical member of the bent ends of plates 6 and the reinforcing channel bar 14 under plates 6,

diate the channels by the rivets 20.

The end platforms of the car are also preferably constructed with the channels running lengthwise the car as in Fig. 2, and the ends are finished by the channel bar 18 secured by rivets 9 to the bases of the channels in plates 6L and to the plates inter'nhee channel bar 18 extends the width of the car, and maybe straight or curved and form the bumpers at the ends of the car'. The end platformz shown in Fig. 2, may be secured to the main floor section of thecar shown in Fig. 1, in the same manner that the sections 6 and 6 are connected in Fig. 4.

By riveting the bottom vmembers of the channeled projections in plate 6a to the bottom flange of the bumper channel bar 18, and the plate 6a at points between the chan` nels to the top flange of the said bar 18, I secure a substantial end construction so that any blow that the car .may receive will be transmitted to the steel plates 6a and 6 which being more or less yielding will give and thus prevent any material damage except from a very heavy blow.

By providing the floor plates with ,deL pending channeled projections they will be self sustaining without the use of cross bearers, and by forming the channels at the junctures of the plates, the latter can be secured together in a plane below the floor proper, thus leaving the latter free from any projections which would interfere with or necessitate recessing or trimming the floor covering.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described but Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. A floor for cars consisting of metal plates each bent downwardly and outwardly at its side edges, the outwardly projecting portions of the depending, members overlapping and securing means uniting said overlapping members, the said downwardly and outwardly projecting members forming channeled projecting members extending transversely of the car Hoor and open at thetop. j

2. A floor for cars consisting ,of metal being riveted to the naiasaa plates having downwardly and outwardly bent edges7 an outwardly bent edge of one plate overlapping an outwardly bent edge of the next adjacent plate and forming a .depending projection open at the top andl extending transversely of the car Hoor, securing means uniting the overlapping members of said projections and a lioor cover: ing resting on the plates.

3. A oor for cars consisting of metal plates having downwardly and outwardly bent side edges, an outwardly bent edge of one plate overlapping an outwardly bent edge of the other plate and forming a channel open at the top and extending transversely of the car floor, securing means uniting said overlapping members of the channel, a floor covering resting on the plates and securing' means passing up through the plates and into the said covering.

4. A floor for a car composed of connected plates having depressions forming channels extending transversely of the car floor, and other plates having similar channels extend ing lengthwise the door, the two sets of plates being connected.

5. A steel floor for cars composed of metal plates having bent edges, the bent edges of two adjacent plates forming a channel open at the top, the channels of some of the plates extending transversely of the car floor, and the channels of other plates extending longitudinally of the ioor, and a floor covering for the said plates.

6. A floor for cars composed of steel plates having channeled projections extending lengthwise the car floor, and a U-shaped channel bar secured to and covering the outer ends of the plate and forming the car bumper.'

7. A floor for cars composed of steel plates having channeled projections extending lengthwise the car floor, and a channel bar covering the ends of the plates and forming the car bumper, the lower flange of said bar being riveted to the lower chords of the channeled projections and the upper flanges plates intermediate said channeled projections.'

In testimony whereof, I have signed this specification in the presence of two subs scribing witnesses.
